Hi Rajesh,
I would start by deriving the shape of the Blackman window as an array. This is then normalised to 0dB and becomes your FFT filter kernel. Upon convolution with your 'dirty' signal it will attenuate your undesired frequency content. Look into multiplying two spectrums together and the inverse FFT.
I hope that helps,
Keith
